Puffed grain includes ancient grains such as popcorn as well as puffed rice. Modern puffed grains are often created using high

temperature, pressure, and/or extrusion,called puffing machine or wheat,corn puff machine ,puff gun machine so on.

Ingredients for puffed rice can be as simple as rice alone and with salt for taste. Commercial products such as Rice Krispies,

Corn Flakes, and Corn Pops,cereal bar,breakfast bar  mix many ingredients into a homogeneous batter. The batter is then

formed into shapes then toasted and/or extruded.

Puffed grains are popular as breakfast cereals and in the form of rice cakes. it is easy to recognize that cereals came from

whole grains, the expansion factor for rice cakes is even greater, and the final product is somewhat more homogeneous.

High pressure puffed grain is created by placing whole grains under high pressure with steam in a containment vessel. When

the vessel's seal is suddenly broken, the entrained steam then flashes and bloats the endosperm of the kernel, increasing its

volume to many times its original size.the upgrade puff machine principle is same just do some change on machine more

safty and handle.
